HYDROCARBON-HEATER.

SPECIFICATION forming' part of Letters Patent No. 670,769, dated March 26, 1901.

Application filed November 12, 1900. Serial No. 36,237. (No model.)

To all whom t may concern:

Beit known that I, AUGUST FILLGRovE, a citizen of the United States, residing at Ironton, in the county of Lawrence and State of Ohio, have invented new and useful Improvements in Hydrocarbon-Heaters, of which the following is a specification.

This invention relates to new and useful improvements in hydrocarbon-heaters, and is especially adapted for use where it is desired to employ natural gas for heating purposes.

The primary object is to provide a device of simple construction which is adapted to thoroughly disintegrate the gas supplied thereto and which will consume all of the particles of the hydrocarbon and discharge hot air which is free of objectionable odors.

With this and other objects in View the invention consists in providing a casing having a feed-pipe therein, which is provided with a suitable number of burners arranged in alinement with each other and adapted to discharge the gas fed thereto upon oppositelyinclined deectors which are arranged within the casing. These dei'iectors are secured to the walls of the casing and also extend transversely of said casing at the center thereof and are adapted to be heated by the gas-jets and will disintegrate the unconsumed particles of the gas escaping from the flame.

The invention also consists in certain novel features of construction and combination of parts,which will be hereinafter fully described and claimed, and illustrated in the accompanying dra wings,showing the preferred form of my invention, and in which- Figure 1 is a section on line a; w of Fig. 2. Fig. 2 is a section on line y y of Fig. 1.

Referring to the drawings by numerals of reference, 1 is a casing, preferably formed of sheet metal and having an inlet 2, arranged in the front face thereof at a point above the bottom, and an outlet 3 in the front face adjacent to the top. The bottom 4. of the casing is preferably provided with a cover 5, of asbestos or other similar insulating material. An inwardly-extending flange 6 is arranged at the lower edge of the inlet 2 and is adapted to form a flue, whereby the air is conducted directly to the burners used within the apparatus. Parallel gas-distributing pipes 7 and 8 are arranged within the casing adjacent to the bottom thereof and are connected at one end by means of an elbow 9er in other suitable manner.

A feed-pipe (not shown) is adapted to be secured to the free end of the lower distributing-pipe 8, and a mixer 10 is provided at the free end of said pipe 8, whereby a mixture of gas and air may be discharged from the burners 11. These burners preferably comprise small tubes arranged upon the upper surface of the upper distributing-pipe 7, said burners being in alinement with each other.

A rectangular casing 12,formed,preferably, of sheet metal, is fitted within the heater between tne inlet and outlet thereof, and secured to the inner surface of the front and rear walls of this casing are deflectors, each vof which preferably comprises a straight body portion 13, which is adapted to be secured to the wall of the casing, and an inwardly-extending curved portion 14., which forms the deflector proper.

Additional deiiectors 15 are arranged one above the other in the center of the casing and between the ends of the deflect-ors 14. Each of these deflectors 15 is preferably formed in one piece of sheet metal bent at the center and inclined in opposite directions, as shown in Fig. 2. Downwardly-extending flanges 16 are arranged at the ends of these deflectors, and said flanges are adapted to be secured to the side Walls of the casing 12 in any suitable manner.

When gas is admitted to the distributingpipes 7 and 8, the same iirst passes through the mixer 10, and this mixture of air and gas is discharged through the burners 11, Where it is ignited in any suitable manner.

The jets of gas will thoroughly heat the inclined deflectors arranged thereabove, and the unconsumed particles which escape from the ames will upon contacting with the IOO inwardly-extending defieotors secured to the opposite Walls of the inner easing, transversely-extending oppositely-inclined deiiectors secured to the end Walls of the inner casing, and alternating with the remaining defiectors, said oppositely-inclined defiectors being arranged above the burner and adapted to be heated thereby.

In testimony whereof I afX my signature in presence of two witnesses.

AUGUST FILLGROVE. Witnesses:
